The height of the tree is 2.25 m. The problem is related to quantitative comparison.

A quantitative comparison is a problem with two objects having different quantities but they can be increasing by the same factor.

Kayla is 1.85 m tall and she stands 23.1 m away from the tree. At the same time, a tree's shadow near her is 28.15 high. Determine the height of the tree!

We have:

If the tree's shadow is longer than Kayla's shadow, the tree's height is also higher that Kayla's tall. The tree's height is

Kayla's tall/tree's tall = Kayla's shadow/tree's shadow

1.85/tree's tall = 23.1/28.15

Tree's tall = (28.15 × 1.85)/23.1

Tree's tall = 2.25 m

Hence, the height of the tree that has a shadow of 28.15 meters is 2.25 m.

The caffeine per ounce in the final mixture of green and instant tea is 40.08 mg.

Based on the data we know quantity of caffeine in an ounce of instant tea is 1368 mg and in green tea is 480.96 mg. So, calculating amount of caffeine in instant and green tea.

Amount of caffeine in instant tea = 24 × 57

Amount of caffeine in instant tea = 1368 mg

Amount of caffeine in green tea = 12 × 6.25

Amount of caffeine in green tea = 75 mg

Total caffeine in the mixture = 1368 + 75

Total caffeine in the mixture = 1443 mg

Total amount of mixture = 12 + 24

Total amount of mixture = 36

Amount of caffeine per ounce in the mixture = 1443/36

Amount of caffeine per ounce in the mixture = 40.08 mg

Hence, the caffeine in mixture is 40.08 mg.

Step-by-step explanation:

Given the angle 10 let's add 360 and see if the angle is in the interval.

However,

[tex]10 - 360 = - 350[/tex]

Answer:

Green Graph:  y = x - 6

Red Graph: y = -3/2 + 7

Step-by-step explanation:

Slope intercept form is represented by the formula:

y = mx + b

m is your slope

b is the y intercept

Another thing to note is that, when m is negative, the graph will point to the left, while when m is positive in will point in the right

For the green graph, the line intercepts at -6, so that will be your b value.

the slope is positive 1 because if your count up from -6 and count across to point (1,-5) you get 1/1

Put these pieces of information in your formula and you get

y = x - 6

You can use the same process to find the equation of the red line. However, the slope will be negative since the graph is pointing to the left side of the coordinate plane.

Answer:

Graph 1:  y = x - 6

Graph 2: y = -3/2 + 7

It takes about 16 years to reach the population size of 22000.

Population growth is the term used to describe changes in population size over time, which can be either positive or negative. The population growth formula is [tex]P=P_0\times e^{rt}[/tex]. Here, P is the total population size after time t, P₀ is the initial population size, r is the rate of growth, and e is Euler's number (e=2.72).

Given the total population, after time t is 22000, the initial population is 10000, and the rate is  5%.

Then, the time is calculated as,

[tex]\begin{aligned}22000&=10000\times e^{(0.05\times t)}\\\frac{22000}{10000}&=e^{(0.05\times t)}\\\ln(2.2)&=0.05\times t\\t&=\frac{0.788}{0.05}\\&=15.76\\&\approx16\end{aligned}[/tex]

Lines are straight with little depth or width. Perpendicular lines, intersecting lines, transversal lines, and other types of lines will be covered. An angle is a shape formed by two rays emerging from a common point. In this field, you may also come across alternate and equivalent angles.

The angle is defined as the span between two intersecting lines or surfaces at or close to the point where they meet.

When a transversal connects two coplanar lines, alternate interior angles are generated. They are on the inside of the parallel lines, but on the outside of the transversal.

The slope of a line through the two points is (y2-y1) / (x2 - x1).

The slope of a line:

The slope of a line is a measure of its steepness. Mathematically, the slope is calculated as "rise over run" (change in y divided by change in x).

Here we have to find the slope of the line.

Data given:

Point one has the coordinate = (x1, y1)

Point two has the coordinate = (x2, y2)

So the slope of the line(m) =( y2 - y1) / (x2 - x1)

The value of the variable x when the distance between two points is 10 is equal to 13 or 1.

As given in the question,

Given two points (7, 5) and (x, -3)

Distance between two points  (7, 5) and (x, -3) is equal to 10 units

Distance = √ ( y₂ - y₁ )² + ( x₂ - x₁ )²

⇒ (10)     = √ ( -3 -5 )² + ( x - 7 )²

⇒ 10      = √ ( -8 )² + x² - 14x + 49

⇒ 10²    =  64 + x² - 14x   + 49

⇒ 100   = 113 +  x² - 14x

⇒ x² -14x + 13 = 0

⇒ x² -13x -x + 13 =0

⇒ ( x - 13) ( x - 1) = 0

⇒ x = 13 or 1

Therefore, the value of the variable x for the given distance and points is equal to 13 or 1.

The effect on the gravitational force if:

a. Both masses are multipled by 3:  the gravitational force becomes 9 times.

b. The distance between centers is X4:  the gravitational force gets reduced by 16 times.

c. One mass is X2 and the other X3 :  the gravitational force becomes 6 times.

d. The distance is divided by 2:  the gravitational force becomes 4 times.

e. The distance is divided by 2 and one mass X3:  the gravitational force becomes 12 times.

We know that the gravitational force between two objects is given by,

F = Gm1m2 / r²                  ...........(1)

We need to find the effect on the gravitational force if

a.  Both masses are multipled by 3

F1 = G(3m1)(3m2) / r²

F1 = 9 Gm1m2 / r²

F1 = 9F                      ...........(from equation (1))

Thus the gravitational force becomes 9 times.

b. The distance between centers is X4

F2 =  Gm1m2 / (4r)²

F2 =  Gm1m2 / 16r²

F2 = 1/16 ( Gm1m2 / r²)

F2 = 1/16 * F                     ...........(from equation (1))

Thus the gravitational force gets reduced by 16 times.

c. One mass is X2 and the other X3

F3 = G(2m1)(3m2) / r²

F3 = 6 * Gm1m2 / r²

F3 = 6F                     ...........(from equation (1))

Thus the gravitational force becomes 6 times.

d. The distance is divided by 2

F4 =  Gm1m2 / (r/2)²

F4 =  Gm1m2 / (r²/4)

F4 = 4 ( Gm1m2 / r²)

F4 = 4F                     ...........(from equation (1))

Thus the gravitational force becomes 4 times.

e. The distance is divided by 2 and one mass X3

F5 =  G(3m1)m2 / (r/2)²

F2 =  3Gm1m2 / (r²/4)

F2 = (3*4) ( Gm1m2 / r²)

F2 = 12 F                     ...........(from equation (1))

Thus the gravitational force becomes 12 times.

Answer:

y = 1/5x -5

Step-by-step explanation:

Slope intercept form is y=mx + b where m is the slope and bb is the intercept. Let's find the slope first. This is rise over run, so we take the difference of two points' y-coordinates and divide it by the x-coordinates' difference.

This gives us [tex](-4--6)/(5--5)[/tex], or [tex]2/10[/tex], which simplifies to [tex]1/5[/tex]. This is our slope. Now we have y = 1/5x + b. We now plug in a point to this equation to get b. Plugging in (-25, -10) gives us [tex]-10 = 1/5*-25 + b[/tex], or [tex]-10 = -5 + b[/tex]. From this we get that b = -5. So, our equation is y = 1/5x -5

where m is the slope and c is the y-intercept.

m = y2-y1 /x2-x1

m = 4-3 / 16-12 = 1/4
